What's with BAT?

I’ve noticed that, over the last few years, BAT tube preamps have gone almost exclusively to the 6H30 tube. No more tube rolling like in the older preamps, such as my VK-3i. Any ideas as to why this has happened?

From my conversations with him, he states most haven't used the 6922 in a way that achieves best performance. So, no matter what, there will be many theories.

Since the 6922s were mentioned here, I thought this may be of some interest. rodman99999, I purchased some tubes second hand through a member here who bought them through Andy's Vintage Tube Service. His site seems to offer more initial info and the prices are somewhat lower than Upscale Audio. The tubes I bought are very good, still in use in the unit I installed then in.

Maybe instead of "musical" I should have said expressive? Your response included a lot of useful info. I've used Upscale Audio in the past. Thank you.

Any recommendations for musical and quiet tubes? Any variant? 7308 ECC88 6N23P Rodman99999, What is your source for the Seimens?
